FAVOURITE VERSION OF OPTIMUS PRIME?

Everybody loves Optimus Prime (except Megatron of course, but he doesn't really like anyone), and of course, everyone's got their favourite version of Optimus.

I'm gonna go out on a limb and guess most of you probably like the G1 version, but I thought it might be interesting to see how many of you prefer another version.

I, for example, am kinda fond of the Unicron Trilogy version (specifically, his Cybertron version), because I really like how he can combine with other transformers, and I just generally like the look of him. I guess the Revenge of the Fallen Optimus can do this too, but I've never really liked the look of the Bayformers.
